Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to a laser welding positioning tooling. Background Art

[0002] At present, laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. It has been successfully applied to the precise welding of micro and small parts. Since laser welding is a commonly used welding technology, it is necessary to optimize the laser welding equipment.

[0003] For example, a laser welding positioning tooling is disclosed in the Chinese utility model patent with the publication number CN217571599U. In the above prior art, although laser welding can be carried out on multiple parts simultaneously, greatly improving the working efficiency of laser welding, the welding of parts by laser is usually on two or multiple surfaces. After the welding of one surface is completed, it is necessary to manually remove the part from the fixing device, turn it over and install it again for welding. This process is not only cumbersome and affects the welding efficiency, but also easily causes the welding position to shift during multiple installation and fixing processes, resulting in welding errors. Therefore, it is necessary to design a laser welding positioning tooling that can automatically turn over the part after the welding of one surface of the part is completed, rather than manually disassembling and turning it over. Summary of the Utility Model

[0004] To solve the technical problem that the manual disassembly and turning over of parts by workers after welding one side affects the welding efficiency, the utility model provides a laser welding positioning tooling.

[0005] The utility model is realized by the following technical solutions: a laser welding positioning tooling, including a welding table, a laser welder is arranged on the welding table, a plurality of parts are arranged on one side of the laser welder, a fixing component capable of fixing the parts and performing welding positioning is arranged on the welding table, a turning component for automatically turning over the parts during welding is arranged on the fixing component, a positioning plate with a turning groove is arranged on one side of the welding table, the fixing component includes two fixing plates arranged inside the turning groove and a plurality of fixing blocks fixedly installed on each fixing plate, and a fixing groove adapted to the parts is arranged on one side of each fixing block.

[0006] Through the above technical solutions, the parts are fixed on the fixing component for welding. After the welding of one side is completed, the turning component will automatically turn over the parts.

[0007] As a further improvement of the above solution, a threaded column is rotatably installed on one side of one of the fixing plates, and one end of the threaded column threadedly penetrates through the positioning plate and extends to the outside of the positioning plate to be fixedly installed with a turning block.

[0008] Through the above technical solution, when the threaded post rotates, the fixed plate will move, thereby clamping and fixing the parts.

[0009] As a further improvement of the above solution, the turning-over assembly includes a servo motor arranged on one side of the positioning plate and a connecting rod fixedly installed on the output end of the servo motor. One end of the connecting rod penetrates through the positioning plate and extends into its interior to be fixedly installed with the adjacent fixed plate.

[0010] Through the above technical solution, when the servo motor starts, the connecting rod will drive the positioning plate to rotate, thereby turning over the parts.

[0011] As a further improvement of the above solution, a plurality of sliding grooves are formed in the welding table, and two sliding blocks are fixedly installed on one side of the positioning plate. Both of the two sliding blocks are slidably matched with the adjacent sliding grooves.

[0012] Through the above technical solution, when welding different parts, the positioning plate can be replaced, which is convenient for welding different parts.

[0013] As a further improvement of the above solution, a first magnet is fixedly installed on one side of the positioning plate, a second magnet is arranged on one side of the first magnet in cooperation, and a connecting plate fixedly installed with the welding table is fixedly installed on one side of the second magnet.

[0014] Through the above technical solution, the cooperation of the first magnet and the second magnet can prevent the positioning plate from moving during welding.

[0015] As a further improvement of the above solution, a support column is fixedly installed on one side of the positioning plate, a positioning rod is rotatably installed at one end of the support column, and a positioning pointer is fixedly installed at one end of the positioning rod.

[0016] Through the above technical solution, the positioning pointer can simply indicate the welding center position, which is convenient for maintenance personnel to inspect and maintain the equipment.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] With the fixing component and the turning-over component of the present utility model, the parts to be welded are fixed by the fixing component. After welding is completed, the turning-over component will automatically turn over the fixing component and the parts, so that the laser welder can continue welding. Such a setting can not only perform positioning welding on the parts, but also automatically turn over the parts that have been welded on one side, without the need for staff to manually disassemble, turn over and reinstall the parts, improving the welding efficiency. At the same time, it also allows the staff to control multiple welding machines simultaneously, improving the work efficiency. Description of the Drawings

[0024] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] Please refer to Figures 1 - 3 , a laser welding positioning tooling in this embodiment includes a welding table 1, a laser welder 2 is provided on the welding table 1, multiple parts 3 are provided on one side of the laser welder 2, a fixing component capable of fixing and welding and positioning the parts 3 is provided on the welding table 1, a turning-over component for automatically turning over the parts 3 is provided on the fixing component, a positioning plate 6 with a turning-over groove is provided on one side of the welding table 1, the fixing component includes two fixing plates 401 arranged inside the turning-over groove and a plurality of fixed blocks 402 fixedly installed on each fixing plate 401, a fixing groove adapted to the parts 3 is provided on one side of each fixed block 402, a threaded column 7 is rotatably installed on one side of one of the fixing plates 401, one end of the threaded column 7 threadedly penetrates the positioning plate 6 and extends to the outside thereof to fixedly install a rotating block 8, the parts 3 are fixed on the fixing component for welding, and when one side is welded, the turning-over component will automatically turn over the parts 3.

[0026] Refer to Figures 1 - 3 , the turning-over component includes a servo motor 501 arranged on one side of the positioning plate 6 and a connecting rod 502 fixedly installed on the output end of the servo motor 501, one end of the connecting rod 502 penetrates the positioning plate 6 and extends to the inside thereof to be fixedly installed with the adjacent fixing plate 401, when the servo motor 501 is started, the connecting rod 502 will drive the positioning plate 6 to rotate, so as to turn over the parts 3.

[0027] Refer to Figure 1 andFigure 2 On the welding table 1, a plurality of sliding grooves are provided. On one side of the positioning plate 6, two sliding blocks 9 are fixedly installed. Both of the two sliding blocks 9 are in sliding fit with the adjacent sliding grooves. On one side of the positioning plate 6, a first magnet 13 is fixedly installed. On one side of the first magnet 13, a second magnet 14 is engaged. On one side of the second magnet 14, a connecting plate fixedly installed with the welding table 1 is fixedly installed. When welding different parts 3, the positioning plate 6 can be replaced, which is convenient for welding different parts 3. The cooperation of the first magnet 13 and the second magnet 14 can prevent the positioning plate 6 from moving during welding.

[0028] Combined with Figure 1 and Figure 2 On one side of the positioning plate 6, a support column 10 is fixedly installed. At one end of the support column 10, a positioning rod 11 is rotatably installed. At one end of the positioning rod 11, a positioning pointer 12 is fixedly installed. The positioning pointer 12 can simply indicate the welding center position, which is convenient for maintenance personnel to inspect and maintain the equipment.

[0029] The implementation principle of a laser welding positioning tooling in the embodiment of the present application is as follows: When a large number of the same type of parts 3 need to be welded, use the sliding block 9 to slide the positioning plate 6 onto the welding table 1 and fix it with the first magnet 13 and the second magnet 14. Then rotate the threaded column 7 to vacate the distance between the two fixing plates 401. Then place the part 3 into the fixing groove of the fixing block 402, and then rotate the threaded column 7 to fix it. In this way, welding can be carried out. When one side of the welding is completed, the servo motor 501 set in advance will be started. Because the welding time is roughly the same, only need to set it in advance so that the servo motor 501 can start at the right time to rotate and turn over the part 3 and the fixing plate 401. In this way, reverse side welding can be carried out, without the need for workers to manually disassemble, turn over and reinstall the part 3, improving the welding efficiency. And using the positioning rod 11 and the positioning pointer 12 can simply locate the welding center point, which is convenient for workers to inspect the welding machine. Because long-term use will cause the machine accuracy to deviate, the positioning pointer 12 can be simply used to distinguish. If the deviation is too large, maintenance is required. Such a setting can not only position and weld the part 3, but also automatically turn over the part 3 that has been welded on one side, without the need for workers to manually disassemble, turn over and reinstall the part 3, improving the welding efficiency. At the same time, it also allows workers to control multiple welding machines at the same time, improving the work efficiency.

[0030] The above implementation manner is only the preferred implementation manner of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
